Original fail message may have been misleading to some people. They may have thought it was a complication with the bot and could lead to spamming of DMs to bot developer.
Fixed typo in my GitHub name after changing.
* feat: add TS devOnlyServer plugin
This plugin will send an error message when the command is ran outside of the specified guild id(s).
If there is no `perFail` message provided, the code will provide an error.
* feat: edit devServerOnly plugin
EDIT: Checks if the fail message exists.
* refactor: changed name of plugin
Changed name of plugin devOnlyServer.ts to serverOnly.ts
* refactor: changed name of plugin on sample command
Forgot to change name of plugin on the sample command during previous refactor.
* refactor: update default failMessage parameter.
Correct default fail message.
